I'm having the same problem with my 1220c HP printer. I am using Windows XP as well, but I have my doubts that the problem is caused by the operating system. I am using the most current drivers offered by HP, and my mnachine is absolutely state of the art (AMD 2100 w/ 768 megs of ram, etc.) I desperately need to get this system to start printing. Does anybody have any suggestions? I've spent a whole lot of money and time on my equipment, and I cannot afford to have it just sitting here!
